530d tuning box's

Recommended Posts

I have a tuneit box as a temporary measure till I get a map. They aren't cheap however retailing at 300-500 pounds new. I'll be selling it soon if you're interested. I noticed the car had 'more teeth' while driving and better fuel economy. I would like a map as it's physically invisible ;-)

Remap is better but tubing box works

I have a remap and I also have a tuning box ready to go on so I'm gonna try them both together and found a few threads where people have had nice results.

I need to recover from a knee op so can't drive just yet but watch this space.

Remap or nothing IMO

 

All the tuning box does is intercept the signal from the ECU fool the car into throwing more fuel in, yes they work to an extent, but a proper remap is a much better option, I've had both and would not use a tuning box again.

If you can stretch to a remap then I'd personally go for that, the cheap tuning boxes are raw in what they do, and basically lie to the ecu, the expensive tuning boxes aren't really that bad but your looking at roughly the same price as a map, unfortunately these comments of tuning boxes on top of maps are not the best idea, if it's mapped it shouldn't need a tuning box, if the mapper knows the m57 engine and its safe limits he'll map your car to around them limits, fuel is not such an issue as boost but if you fit one of them tuning boxes that raise the rail pressure your firing more fuel in ruining the AFR increasing manifold pressure and EGT to maybe an unsafe level, at the end of the day I could get my car mapped take it home turn up the boost and add a little more fuel duration and make it faster but is be on borrowed time.

I'm no mapper but with the right software I used to change and adapt my own maps to my taste on my passat with a little help from others, it was running about 28psi or 1.8 BAR of boost and running around the 210bhp with 340ft/lbs of torque, and it was doing it safely without a piggy back tuning box.

Anybody that reports better fuel consumption with piggy backed timing box hasn't realised that the tuning box lies to the ecu to inject more fuel, unless calculated by tank to tank measurements at the fuel pump the obc and ecu believes it's injecting less fuel giving itself a false mpg reading, as the mpg is calculated off the fuel injection quantity maps and maf calculating the fuel usage per stroke then using that info for your mpg, if the ecu is being lied too then these figures will never be true :)

Hi,

 

As per burnzybubbles post above. With a good re-map there's no reason at all to try and run a tuning box on top. I previously also had a TuneIt box on my car, and when I turned up the control to number 9, my computer MPG over a week or two went down to an indicated 22 MPG ! I thought for 22 MPG I may as well and get an M5 ! I took the cheaper option of removing the Tuning Box and selling it off and getting a good specific re-map done. 

 

A re-map is physically invisible, but it's easily electronically detectable. 

 

My recommendation would be to use the higher end, knowledgeable re-map specialists - names like Evolve, E-maps (Simon), B&W Chiptune, DMS automotive spring to mind for instance. 

 

Cheers, Dennis!

Nudge me when you're done, I was considering this also

Got a Bluespark automotive tuning box, used one on my old Volvo S60 D5 with good results.

Can't see the car happy with the box turned up to full whack but midway should see some gains.

Hi 

 

Digidick - even at the TuneIt box on it's highest setting, the parameters used in it's map are well within specified tolerances for the engine and 'easily' available to the consumer mapping choices. If you were to get a custom re-map for your own car using a rolling road for before/after comparisons and someone who knows how to re-map on the fly (to an extent) you can opt for a more aggressive map. Most tuners won't really wish to push the parameters too much though. For customers who are indeed looking for an even more aggressive map, I think the specialists may wish to request the customer sign an agreement indicating that so if the engine doesn't like it later and things go wrong, they'e covered. Even in those scenario's the parameters are still only changed to levels considered 'useable' to an extent on public roads. When you get to motorsport or track level usage, you can have yet more aggressive remaps done. Even at that level, you'd still be within tolerances for the engine itself.

 

With the TuneIt box, I have a strong feeling that it was just the 'extra fuelling' parameter that was changed. Of course as a result, the car felt quicker! When I first had it done, I set the box to the initial number 1 position and I couldn't tell any difference. After a week I went to position 3 and still couldn't feel anything, I 'thought' there was 'some' improvement at position 5 which I went to a few days later, but only when I went to position 9 did I feel anything! - it was then when I watched my MPG plummet over perhaps 7-10 days down to 22mpg !! I took the TuneIt box off and In contrast when I had my custom re-map done a few months later, my MPG figure over the following 2-3 weeks went from usually indicating 31.7 MPG to 32.4 MPG (my commute at the time was 7 days a week, same route of 50 miles per day with 85% on the motorway and the rest in town - a total opposite to what I found with the TuneIt. . A 'proper' re-map is the proper/correct route to take in my opinion.

 

Cheers, Dennis!

We'll the tuning box has been on for two weeks and it's made a big difference, she drives great.

I've always felt my remap was only a mild one and although it made a nice difference I felt it was lacking a little.

The tuning box on top seems to make it rev more like a petrol and power delivery is much stronger now in 2nd and 3rd and awesome in 4th. It was purchased used from Jimmy and it's a Bluespark Automotive Tech 2 box which gets some good reviews online but not much info when used on a BMW.

So worth a go if you can get one quite cheap, see what ya think.

You have no idea if you are doing any long term damage, the tuning box is designed to work with a standard engine's parameters, running one on top of a remap is potentially dangerous to the engine.

 

Also, the 5 speed GM autobox is a know weak point, pushing extra power & torque through it usually ends in expensive failure.

I shadow rich D's comment, have you logged boost or had it on the dyno, checked emp or egt, all things that can drastically shorten engine, turbo and gearbox life.

I don't drive it like a nutter so won't be under constant stress but even steady acceleration is smooth and effortless so for now it's staying on.

Turbo only 35k old and has had regular oil changes since so in fine fettle.

If you can find any evidence my actions have resulted in destruction then please point me to it.

Hi,

 

With the advancements in technology and the knowledge gained by re-map specialists, it's now really quite unnecessary to have a tuning box 'sit on' top of a remap - or vice versa. All the higher end, specialist and experienced re-map specialists would basically laugh at this notion if asked by a customer to do it as all the parameters that need adjusting/changing etc can all be accessed via the re-map route.

 

That said, you've gone ahead and done this so it'll be interesting to see your longer term views with it. As it's a bit of a 'gamble' or 'test' hopefully the results over time will mean it all seems to work ok. There's no practical way of determining if destruction is occurring short of you opening the engine and gearbox up every month to check all the components etc! however, much higher up in the chain of knowledge and where direct R&D has or is carried out with ECU's and re-maps etc, then as mentioned previously, there are 'tolerances' that manufacturers of cars sold to the general public build into their engines. An oem map will be a compromise so that many examples of the car sold can work well as a motorway mile muncher or a hardly driven local shopping trolley. A specalist re-map will 'dial out' some of those compromises and as  a result, those specific parameters that are changed etc will be known about. If you then 'add on' another device to change parameters that have already been changed, then you 'don't know' if the parameters have been pushed out near or past the known good levels as conducted by the R&D done previously. In my own experience, it seemed the tuneit box I had focused its changes on fuelling, and simply 'pumped' more fuel in order to get the feeling of a performance increase.When I saw that my MPG had gone to 22mpg, I really did think, that's M5 levels of fuel consumption! So, in your case, the 'risk' of various parameters being pushed too far are greater with the setup you are running. The follow on risks are of course the more strain on engine and gearbox components which will shorten their useful life. Quite how long it's shortened by is not easily determinable, however if you look at the benchmark the manufacturers make their vehicles and drivetrain components, say a life expectancy of 7-10 years, then by operating any aspect of it near or past recommended levels will bring that life expectancy down - I wouldn't say 'drastically' down, but certainly, over time noticeably reduced.

 

Cheers, Dennis!

Just don't come on hear whinging when something goes bang, I'm thinking Turbo, HPFP, Injectors, Gearbox. Still your motor and your money so good luck, I just don't want to read about the inevitable downside when it comes.
